LAWRENCE — Two women were killed and another man was flown to the hospital in critical condition when a car slammed into a parked tractor-trailer in the shoulder of I-95 early this morning, according to state police.

The Volkswagen – with four people inside – crashed into the tractor-trailer around milepost 8.8 around 1 a.m., said Sgt. Adam Grossman.

Two women who had been in the backseat died at the scene, and a man who had been in the front passenger seat was extricated out of the crushed car and rushed to a local hospital, where he remains in critical condition this morning, Grossman said.

The driver only suffered minor injuries, Grossman said.

The ramp from Route 1 southbound onto I-95 south was closed for hours, the sergeant added. The investigation into the crash is ongoing, he said.
